BioAPI?

The BioAPI Specification defines an open system standard

application program interface (API) that allows softwareapplications to communicate with a broad range of biometric

technologies in a common way.

Biometric operations

BASIC FUNCTIONS

Enroll User Enroll

Creates template (stored inuser account DB and/or BSPDB)

Verify asserted identity

(1:1) Verify

Live input matched againstone stored template

Discover Users identity(1:N)

Identify Live input matched against

set of stored templates

PRIMITIVE FUNCTIONS

Capture Captures biometric data from

sensor

CreateTemplate Creates enrollment template

NewTemplate can be anadaptation of a StoredTemplate

Process Converts intermediate to

processed BIR for matching

Process with Aux BIR

VerifyMatch Performs 1:1 match

IdentifyMatch Performs 1:N match against

specified DB

Import Imports non-real-time data for

processing

Technology modules (BSPs)

Technology modules instantiate the service provider interface, biometricalgorithms, and device interface (currently monolithic)

Provide biometric services to applications Biometric engine

Biometric service provider (BSP)

Can be distributed between platforms (i.e., client/server configuration)

Generally responsible for user interface (GUI), as default

May encompass one or more technologies Typically implemented as a wrapper around an existing SDK

May use proprietary or standard data formats (must be registered)

May support 1:1, 1:N, or both

May include an internal or BSP controlled database

May be instantiated in software or a combination of software & hardware May be a self-contained device May be a combo or hybrid device

May use a dedicated or commodity device
